Objectives: The risk factors associated with herpes simplex virus (HSV) seropositivity in pregnant women in Saudi Arabia are not known. Use of images for any purpose including but not limited to research, commercial, personal, or non-commercial use is prohibited without prior written consent.
To confirm correct surface expression of chimeric receptors on Geneticin resistant cells, FACS analysis was performed. Figure 2.2 (A) Stable expression of chimeric receptors on BW5147 transfectants assessed by FACS. Furthermore, to test if cell bound HD-1 triggers mIL-2 release in a dose dependent manner from FcRIV-ζ cells, a co-cultivation assay with HSV-1 infected fibroblasts was performed. ADCC (Antibody Dependent Cell Cytolysis) assays are normally performed in the laboratory with polyclonal or monoclonal IL-2 pre-activated NK cells. Figure 2.12 MV IgG reaction patterns of individual sera compared in the 5 different assays for measuring IgG. To compare reactivity pattern of individual HCMV IgG immune sera, the CMV-IgG ELISA values were selected to order the serum donors (Figure 2.13).

Monoclonal and polyclonal IgG-dependent activation is reported by the BWCD16-ζ cocultivation with a denatured antigen on a plate or native surface antigens on virus infected cells. The BW transfectants are exclusively activated in the presence of intact IgG (Cytotect® input or undigested IgG in eluate). HEp-2 cells were infected with two RSV A clinical isolates before incubated with increasing concentrations of Palivizumab.


Hep-2 cells were infected with 2 pfu per cell of two different RSV clinical isolates, 5720 or 4732. Mouse embryonic fibroblasts (MEF) were infected with MCMV for 48h and opsonized with different dilutions of immune and non-immune serum pools.
Qualitative differences between viruses were observed, for example, FcγR CD32 was clearly less activated in CMV and EBV settings as compared with HSV or paramyxoviruses. After 72 hpi, cells were incubated with the RSV-specific humanized mAb Palivizumab for 30 minutes at 37°C. CD16 activation in the BWCD16-ζ assay and NK cells degranulation assay is comparable, since both become alike activated in a dose dependent manner after crosslinking. The novel assay can be used as a surrogate test for measuring activation of the host FcγRs and ADCC.
The order of the samples was set according to the percentage of maximal activation achieved with the ELISA measurements.
In some sera, the titer of MV-neutralizing IgG did not correlate with ELISA measurements, while CD16 and CD32 activating MV-IgG showed a better correlation with each other. The order of the samples was set according to percentage of maximal activation achieved with the ELISA measurements. The overall diversity of individual CMV-IgG reaction patterns was larger compared to MV-IgG antibodies.
Infected human fibroblasts with HCMV wild type and HSV-F wild type viruses were incubated with human Fc-FITC. Materials and Methods: This is a hospital-based cross-sectional study that included all pregnant mothers who delivered at King Fahd Hospital of the University (KFHU) over a period of two years (November 2002 to October 2004). The expression of FcRIV-ζ was difficult to assess, since there are no commercially available antibodies. Afterwards, a human polyclonal preparation Cytotect® was used to opsonize this plate (which was previously coated with HCMV- and MCMV-virions) in order to elicit immune complex formation. Cytotect® (Original source of IgG) and the IgG undigested output were able to activate the chimeric receptors.
This could be due to different expression intensity of the chimeric receptors on the surface of the BW5147 transfectants. Specificity of virus detection was ensured by a pool of serum samples not reactive in commercial ELISAs detecting virus-specific IgG (see experimental procedures and data not shown).
After 72 hpi, cells were incubated with log2 dilutions of Palivizumab for 30 minutes at 37°C. After binding of an immune complex Ag-Ab to the CD16, a series of signalling cascades cooperate finalizing in liberation of perforin and granzymes which execute target cell lysis. Afterwards, mouse anti human CD16 was added in different concentrations and incubated for 30 minutes at 37°C. Interestingly, the overall diversity of individual HCMV-IgG reaction patterns (Figure 2.13) was more pronounced compared to MV-immune IgG.
Anti-HSV-1 and anti-HSV-2 IgG and IgM antibodies were determined using type-specific ELISA. Nevertheless, mouse Fc-IgG staining on the surface of half of the transfectants was detected, suggesting the presence of a considerable subfraction of cells to be positive for the construct (Figure 2.2A).
The antigens recognized in this experimental setting are denatured due to the coating procedures.
Mouse embryonic fibroblasts (MEFs) were infected with MCMV for 48h and opsonized with different dilutions of immune and non-immune serum pools.


In parallel, to compare if initial opsonization of the target cell is required for activation, a reverse approach was also performed. IgG and IgM ELISA titers were determined according to the manufacturer’s (Enzygnost, Dade Behring) instructions. Samples with lower measurements were assigned with decreasing percentage of maximal activation until reaching 0%, i.e.
The values regarding sensitivity, specificity, negative predictive value, positive predictive value as well as test efficiency were determined for each of the CMV-IgG assays.
Although HSV-2 has a predilection for the genital mucosae, genital herpes can be caused by either HSV-1 or 2.
For the activation mediated by monoclonal or polyclonal antibodies, MRC-5 cells were infected with 2 pfu per cell of HSV-1. Fc fragment alone does not bind to the antigen since it is not retained in the washing procedure before cocultivation with the effector cells. In parallel, to asses if opsonization of target cell is completely required for activation, a reverse approach was also performed.
CD107a degranulation and mIL-2 secretion respectively were measured at 4 hours and at 24 hours post cocultivation. The data indicated that the RSV-F glycoprotein forms immune complexes on the surface of infected cells when recognized by a humanized mAb, Palivizumab, which are potent inducers of different types of FcγRs. However, differences between viruses were also observed since FcγR CD32 was clearly less activated in CMV and EBV settings as compared with HSV or paramyxoviruses. In conclusion, all established BW transfectants responded when crosslinked by specific mAbs directed to the extracellular domain of the FcγR chimeras. The cutoff value was based on mIL-2 produced by BW transfectants cocultivated with MV-infected targets and sera (diluted 1:4) of 10 ELISA-seronegative donors. In the USA, there is more than 45 million people currently infected with HSV, with <1 million cases diagnosed yearly. However, the size of the virus-specific IgG subfraction activating a distinct FcγRs depends on each particular virus. Both assays show a comparable dose dependent response after CD16 crosslinking at 4 hours incubation.
Likewise, the specificity, positive and negative predictive values of the former assays was 100%, resulting in an efficiency reaching 100%. Using multiple regression analysis, the prevalence of HSV-2 IgG was found to increase in older mothers (p = 0.037). The hBWCD16-ζ assay shows even a higher activation at 24 hours post incubation than the polyclonal NK cells. In conclusion, the resolution of HCMV-specific IgG responses among normal donors revealed an even broader heterogeneity of reaction patterns as compared with MV. No statistically significant association was found between HSV seroprevalence and other socio demographic variables. 24 hpi, grading dilutions of anti-gD HD1 antibody were added and incubated during 30 minutes at 37°C.
